Application of crypto-video watermarking technique to improve robustness and imperceptibiltiy of secret data

In this paper we have proposed novel and innovative Video Watermarking using Pixel Location Based Technique (PLBT) to improve the robustness and imperceptibility of secret data. We have located the pixel values of selected frames of watermarked video with the obtained pixel values of secret watermark image and locate the respective offset values of selected frames of watermarked video as a secret key. Through different types of attacks on watermarked video during transmission, we have demonstrated that original and watermarked video are exactly identical to each other without any loss of information. The simulation and the comparisons results confirmed the improvement in robustness and imperceptibility of hidden watermarked secret data as compare to any other existing techniques.
